KPMG's reports on the financial statements for the fiscal years ended August 31, 2019 and August 31, 2018 contained no adverse opinion or disclaimer of opinion nor were they qualified or modified as to uncertainty, audit scope or accounting principle. During such fiscal year-ends and through December 12, 2019, the date of dismissal,

(i)there were no disagreements with KPMG on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of KPMG, would have caused them to make reference to the subject matter of the disagreements in connection with their reports on PGIM California Muni Income Fund's financial statements for such period, and (ii) there were no "reportable events" of the kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934, as amended.

On December 12, 2019, the Audit Committee and the Trust's Board of Trustees approved the engagement of PricewaterhouseCoopers LLP (PwC), to serve as the independent registered public accounting firm for PGIM California Muni Income Fund's fiscal year ending August 31, 2021, thereby replacing KPMG effective upon completion of their August 31, 2020 audit and issuance of their report thereon. During PGIM California Muni Income Fund's fiscal years ended August 31, 2019 and August 31, 2018 and through December 12, 2019, neither Prudential Investment Portfolios 6, nor PGIM California Muni Income Fund, nor anyone on its behalf, consulted with PwC on items which: (i) concerned the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on PGIM California Muni Income Fund's financial statements; or (ii) concerned the subject of a disagreement (as defined in paragraph (a)(1)(iv) of Item 304 of Regulation S- K) or reportable events (as described in paragraph (a)(1)(v) of said Item 304).

Ladies and Gentlemen:

We were previously principal accountants for PGIM California Muni Income Fund, a series of Prudential Investment Portfolios 6, and under the date of October 18, 2019, we reported on the financial statements of PGIM California Muni Income Fund as of and for the years ended August 31, 2019 and 2018. On December 12, 2019, we were dismissed as independent registered public accountant effective upon completion of the August 31, 2020 audit and the issuance of our report thereon.

We have read the statements made by Prudential Investment Portfolios 6 included under Item 13(a)(4) of Form N-CSR dated April 28, 2020, and we agree with such statements except that we are not in a position to agree or disagree with the statements that (1) the Audit Committee and Prudential Investment Portfolios 6's Board of Trustees approved the engagement of PricewaterhouseCoopers LLP (PwC) to serve as the independent registered public accounting firm, and (2) neither Prudential Investment Portfolios 6, nor PGIM California Muni Income Fund, nor anyone on its behalf, consulted with PwC on items which: (i) concerned the application of accounting principles to a specified transaction, or the type of audit opinion that might be rendered on the PGIM California Muni Income Fund's financial statements; or (ii) concerned the subject of a disagreement or reportable events.

Very truly yours,
